Can't connect Ps3 to Wireless USB Dongle via ICS?

Hi there,

I have an usb wireless dongle and runnig it in ICS mode (Access Point mode). I used the connection wizard for wireless on ps3 in my room and everyting worked perfectly. Then i took the ps3 to the living room (7 meters away) but this time ps3 couldn't connect to the internet (Couldn't obtain an ip adress).

What is the problem?
